Key, then " Amount " key is pressed, whether verification Amount value is correct；
2) light source transmitting lid is opened, full-length ruler is inserted into the hook of driving platform, transmitting lid is shut, presses " self-test "
Key, then " Amount " key is pressed, whether check length is correct.
Hereafter, whether the numerical value of the Amount value and full-length ruler that only need self-test normalized optical template is in critical field
It is interior, if there is no need to do hardware calibration again in standard value.If going beyond the scope, then do hardware calibration.
Four, the communication between computer and host is established
1, the communication cable of host and computer is connected.Then, it opens computer power and host power supply (pays attention to opening master
When electromechanical source the lid of host must be box).
2, communication is established
1) menu on computer desktop is clicked, into login interface；
2) account and password are inputted, enters by " login " and welcomes interface；
3) calibration is clicked；
4) cotton samples parameter is modified
When the numerical value that the standard sample taken and computer are shown is inconsistent, then need to modify numerical value.Click calibration window
Lower left " parameter " inserts standard specimen numerical value in window.Staple fiber is filled out on the left side, and long fibre is filled out on the right.It has filled in and has returned to
Calibrate window.If the numerical value shown on the standard cotton sample and computer taken is consistent, this step is not needed, and is directly entered down
One step.If the numerical value shown on the standard cotton sample and computer taken is consistent, this step is not needed, and is directly entered next
Step.

The test result of dimension.Same standard cotton sample at least takes 10 times, tests repeatedly, deletes the most short of a upper half mean length
Value, deletes the greatest length of a upper half mean length, then be averaged, and the error of upper half mean length is less than 0.5mm,
Same uniformity index will also delete the minimum of a uniformity index, delete the peak of a uniformity index, then take
The error of average value, uniformity index is less than 2%, if having it is a small amount of beyond can repeatedly take several times standard specimen tested, then
It is averaged, various factor bring errors can be reduced in this way.Test terminates to click " completion " key.
2, standard specimen 2 (long cotton samples) are tested
Test method is consistent with staple fiber step is surveyed.
3, terminate when short with long standard sample test, it is necessary to " calibration " key among window lower left, Cai Nengshi
Now calibrate.Electronic data processing accounting calculates the slope after this calibration, the data such as offset.Calibration finishes click " holding ".It clicks and " returns again
Return " return to welcome window." holding " can not be clicked if being not desired to retain this calibration result, clicks directly on " return ".
Six, it measures
In welcome window, clicks Section 2 " detection ", show following picture.
1, it modifies the length standard value of short flannel and establishes the communication of host and computer
1) length value in " shortenning suede " upper right side of window lower left becomes blue, at this point it is possible to modify short flannel length
Standard figures.It does not need to click " shortenning suede " if not needing modification.The standard that the length value of this short flannel must be held with you
Sample is consistent；
2) it if desired checks every time according to shadow curve, is then checked in the box according to shadow curve every time in upper right side and make hook, be not required to
Hook is not made then.
3) communication is established when clicking " starting " because calibrating just now, therefore click " starting " is only needed just to show following window
Mouthful.
2, transmitting lid is opened, in the hook folder that the sampling for having taken cotton samples is combed to insertion driving platform, with hairbrush with stable
Movement to remove wandering fibre and tie other straightening of fibers not and again, has prepared towards leaving the multiple brush fiber in direction of defeated folder
Finish and closes transmitting lid.
3, " test " key on host panel is pressed, test data rolls in communication information column, shows step number and numerical value, directly
To the data transfer ends, upper half mean length, uniformity index, the short fibre content value of cotton fiber are shown.Each sample
Pendulous frequency can be decided in its sole discretion according to user demand.More preferably greater than 8 times, then it is averaged.
4, test terminates, and clicks " return " key of communication information window, and communication window is closed.It is clicked to save data
" preservation " can also click " return " on the wicket of pop-up if " cancelling " directly return welcome window can be clicked by not needing to save
Measurement window is exited in click.Can result be printed or be saved in this window.
Six, it inquires
" inquiry " key of this window lower left is clicked, the originally frame and word of grey mostly can be light, at this point it is possible to select to appoint
Where formula is inquired.Inquiry can also be clicked.
1, detection odd numbers frame is chosen then according to detection odd numbers inquiry；
2, sample number into spectrum frame is chosen then to be inquired according to sample number into spectrum；
3, censorship unit frame is chosen then to be inquired according to censorship unit；
4, operator's frame is chosen then to be inquired according to operator；
